What is SpamAssassin?
SpamAssassin is an open-source software developed by the Apache Foundation and is popular among web hosting users and system administrators.
This software uses complex algorithms and analysis tools to scan and analyze emails and decide whether they are spam or not.
This process is based on various criteria, such as content, sender reputation, subject, authentication, and message content format.
On web hosting services, SpamAssassin is usually included as a default feature that can be activated or set according to user preferences.
How to Enable SpamAssassin in cPanel
How to Enable SpamAssassin
If SpamAssassin is not yet activated on your hosting control panel , you should activate this feature immediately. To activate SpamAssassin, follow these steps:
How to Enable SpamAssassin
Log into your cPanel and navigate to the Email section.
Click the Spam Filter menu
Click the toggle button next to Process New Emails and Mark them as Spam .
SpamAssassin Settings Configuration
After enabling SpamAssassin, you can customize its settings as needed:
Score Threshold : Set the score threshold for marking emails as spam. The default score is usually set to 5.0; you can lower it to filter more spam emails, or increase it if too many legitimate emails are detected as spam.
Whitelist and Blacklist :
Whitelist : Add email addresses or domains that you consider trustworthy so that they are never marked as spam.
Blacklist : Add email addresses or domains that you want to block so that emails from them will be immediately marked as spam.
Viewing SpamAssassin Reports

This helps you understand how effective SpamAssassin is in filtering emails and if any legitimate emails are detected as spam.
How SpamAssassin Works
Once you know how to activate SpamAssassin in cPanel, you also need to understand how it works. SpamAssassin works by applying various analysis techniques, including:
Sender IP Check : View the reputation of the sender's IP address to see if it is frequently used in spam activity.
Subject and Content Analysis : Scans the subject and body of emails to find patterns of words or phrases that frequently appear in spam emails.
Authentication and Encryption : Ensuring emails come from a trusted source.
Bayesian filtering and blacklisting : Using statistical techniques and on line blacklisting to detect spam more accurately.
By collecting the results of all these checks, SpamAssassin assigns a score to each email. If the score exceeds a certain threshold, the email is considered spam and can be deleted immediately or directed to the spam folder.
Here are the details of how SpamAssassin scores emails:
Negative numbers: These numbers indicate that the email is unlikely to be spam, so your overall score is low.
Neutral: A score of “0” means this factor has little impact on the overall spam score.
Positive number: This number indicates a higher probability that the email is spam.
